METHOD OF MAKING ORNAMENTAL SCREENS.

SPECIFICATION forming part of Letters Patent No. 525,593, datedSeptember 4, 1894.

' Application filed April 23, 1894. Serial No. 508,724. (No model.)

To all whom it may concern:

Be it known that I, IRVING E. FOLTZ, a citi-' zen of the United States,residing at Rockford, in the county of Winnebago and State of Illinois,have invented a certain new and useful Improvement in Methods of MakingOrnamental Screens, of which the following is a specification.

The object of this invention is the method of forming ornamental openwork from a single piece of material by cutting it or parts of it 111double convoluted form, with a common center and extending the design soproduced by drawing or separating the two parts a sufficient distance.

In the accompanying drawings, Figure 1, is a face representation of asection of the cut material. Fig. 2, is a face representation of theopen work formed from the cutmaterial shown at Fig. 1, as it re-arrangesitself as the result of being drawn or extended. Figs. 3 and 4 show amodification. The method disclosed by this application is the formationof open work or fanciful or namentation from sheet material, and capableof various uses, and consists in cutting from a sheet of material twoconcentric designs starting opposite each other from the outside, andjoined at the center, and in stretching out the designs thus formed fromtheir outer edges, or ends, a sufiicient distance to produce therequired length.

From a sheet of material of the required size are stamped or cut out thedouble convoluted designs 1, and 2, in this instance tapering in widthas they approach the center 3, where they unite and have border strips4. and 5, attached to their outer ends. By suitable means the borderstrips t and 5 are caused to separate which will cause the coils of theconvoluted designs to separate or pull out, until the required lengthhas been reached when it will appear as shown at Fig. 2, forming aconnecting rod or spindle of a twisted.

or spiral design, gradually tapering from both ends toward the center,presenting a graceful and pleasing appearance.

The design may be produced independently of the border strips by cuttingthem as shown in dotted lines, and for some purposes this may bedesirable.

The design may be stretched to a greater or less degree, and thus bemade to fill spaces of various widths or heights.

It is evident that other designs than a true spiral may be produced, anexample of which is shown at Figs. 3 and 4 in which the design is of adiamond shape when out, and when stretched, a series of angles is formedwhich may be desirable in some instances.

It is evident that the designs may be employed for other purposes thanfor screens as for ornamentation or supports for various articles and ifmade of heavy material may be used for fencing and railing for bridgework, as the object sought is the method of its formation.

In constructing heavy work after the method herein described it may benecessary to stamp out a section of the material instead of cuttingthrough as herein shown.

I claim as my invention- 1. The method of forming designs consisting incutting from sheet material two convolute figures, said figures. beingunsevered from each other at a common center, being continuous with eachother therefrom, and both of them convolving around said center, andstretching out the material forming the design thus produced.

2. The method of forming designs consisting in cutting from sheetmaterial, two convolute figures, said figures being unsevered from eachother at a common center, being continuous with each other therefrom,and both of them convolving around said center, with their outer endsapproximately opposite each other as regards said center, each of saidfigures having joined with it on its outer edge a lateral strip cut fromthe same sheet of material as said figures, and at about the middle ofits length being unsevered from, and continuous with, said figures, thetwo said lateral strips being opposite to, and parallel with each other,and stretching out the material forming the design thus produced.

3. The method of forming designs consisting in cutting from sheetmaterial a row of like designs, each of which designs is formed bycutting out two convolute figures, each of said convolute figures beingjoined to the other at the center, each of said convolute figures havingjoined with it on its outer edge a lateral strip cut from the same sheetof material as said figure, being unsevered from,

and continuous with said figure, said lateral strips extendingcontinuously throughout the entire length of said row of designs, beingjoined in like manner with each member of said row of designs, formingacontinuous and unsevered upper strip, and a continuous and unseveredlower strip, each of said strips being joined with, and unsevered from,and continuous with, each member of said row of designs, and stretchingout the material forming the row of designs thus produced.

4. The method of forming designs consisting in cutting from sheetmaterial a row of like designs, each of which designs is formed bycutting out two convolute figures, said figures being unsevered fromeach other at a common center, being continuous with each othertherefrom,and both of them convolving around said center, with theirouter ends approximately opposite each other as regards said center,each of said two figures having joined with it, one on its upper outeredge, and the other on its lower outer edge respefiively, a lateralstrip, cut from the same shut )5 of material as said figures and as saidrow of designs, being unsevered from and continuous with said figures,said lateral strips extending continuously throughout the Olltil" lengthof said row of designs, being joined 30 in like manner with each memberof said to. of designs, forming a continuous and unsavered upper strip,and a continuous and lllh severed lower strip, each of said strips beingjoined with, and unsevered from, and con- 35
